Featured Capabilities / Case Studies

Scratch-Wound Assay

Scratch-Wound Assay

 

In the scratch wound assay, a pipette tip is used to create a uniform gap, or wound, across each confluent cell monolayer of a multiwell plate. The plates are imaged over time to determine the wound density, which reflects the extent to which cells have migrated into the gap. In our scratch wound assay, cell staining and advanced automated imaging are used to define gap borders, and to measure changes in gap density over time. This minimizes variability, leading to more accurate measurements.

Here, automated imaging was used to define gaps, and to monitor the exact same location in each well over time. Kinetic reads demonstrate the dynamics of cell migration, and show clear differences in migration with the addition of serum. Representative images provide visual confirmation of cell migration over time.

Chemotaxis Assay

Chemotaxis Assay

 

The modified Boyden chamber consists of two chambers separated by a porous membrane. Cells are placed in the upper chamber, and chemoattractant is placed in the lower. Chemotaxis is measured by the migration of cells from the upper to lower chamber. Our chemotaxis assay quantitates this migration by imaging the upper chamber to determine cell depletion.  Measurements can be taken over time to generate dynamic chemotaxis curves.

Here, dilutions of chemoattractant were placed in lower chambers, and equal number of T-cells were placed in upper chambers. By imaging the upper chamber over time, cell migration curves are generated. When the terminal data points for each curve are plotted, a dose-response curve is created to reflect the effect of chemoattractant on cell migration. Such analyses can be used to determine EC50 values, providing a standardized method for comparing various chemoattractants.

Chemotaxis Inhibitor Studies

Quantitative Chemotaxis Inhibition Assays

 

The standard chemotaxis assay can be modified to assess the inhibitory effects of various molecules. In this workflow, chemoattractant is added to the lower chamber of all test wells at the same concentration, while inhibitor is included at various dilutions. As before, the upper chamber is imaged over time to measure cell migration, generating chemotaxis curves. Inhibitors will cause a reduction in the observed cell depletion from the upper chamber.

Here, serial dilutions of inhibitor show dose-dependent reductions in cell migration. By plotting the terminal data points from each curve, a dose-response curve is generated, allowing for IC50 determination for the inhibitor.

Frequently Asked Questions

Need more information on our cell migration assays? Read below, or contact us for answers.

In the scratch wound assay, cells are grown to confluence, then a pipette is dragged across the monolayer to create a gap. Cells are imaged over time to measure the rate at which they fill in the gap.

A Boyden chamber assay consists of two chambers separated by a permeable barrier. Migration of cells from the upper chamber to the lower chemoattractant-containing reservoir provides a measure of cell chemotaxis.

Our cell migration assays achieve reproducible, sensitive readouts of migration rate, and are accompanied by high content imaging of cell monolayers to provide detailed assay images.

Treatments aimed at enhancing or inhibiting migration can be assessed for their effects on cell migration rate.
